Shiyun and Cole had a total of $60. After Shiyun spent
35 of her money and Cole spent $16, the ratio of Shiyun's money to Kennenth's money became 1 : 3. How much money had Cole at first?

Shiyun |
Cole |
Total |
| Before |
5 u |
6 u + $16 |
$60 |
| Change |
- 3 u |
- $16 |
|
| After |
2 u |
|
|
Comparing Shiyun and
Cole in the end |
1x2 =
2 u |
3x2 =
6 u |
|
The amount that Shiyun had in the end is repeated. Make the amount that Shiyun had in the end the same. LCM of 2 and 1 is 2.
Total amount that Shiyun and Cole had at first
= 5 u + 6 u + 16
= 11 u + 16
11 u + 16 = 60
11 u = 60 - 16
11 u = 44
1 u = 44 ÷ 11 = 4
Amount that Cole had at first
= 6 u + 16
= 6 x 4 + 16
= 24 + 16
= $40
Answer(s): $40
